To (LU wl'to'n zl it HI/(Ly concern/.-

Be it known that 1, JOHN B. um, a citi- Zen of the United States of America, and a resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Step-Mitering Machines, of which the following is a specification.

My invention contemplates an improved machine-for step-mitering the ends of cleats such, for example. as the cleats to be employed in making wire-bound box-blanks.

In a machine characterized by my invention the step-mitering is accomplished by means of cutters, and the cleats are cut off at each end by means of circular saws. In this way the proper length is insured for each cleat, and the step-mitering is accomplished in a simple, effective,and highly efficient manner. Furthermore, I provide means for varying the distance between the cutter-heads, so that the step-mitering may be carried on with respect to cleats of different lengths. Again, I provide means for bodily raising and lowering'the cutter-heads, thereby making it possible to employ the machine for operating on cleats or strips of different thicknesses. In addition the cutter-heads are of animproved and highly-efficient form, each head being composed of a plurality of knives mounted obliquely in the head and readily removable for purposes of repair or substitution.

Another important feature consists of the provision of an endless work holder or carrier adapted to receive and bodily carry the cleats forward in the direction required for passing the latter beneath the rotary cutter-heads.

Other advantages and features of improvement will hereinafter more fully appear.

In the accompanying drawings, Figure 1 is a side elevation of my improved step-mitering machine. Fig. 2 is an enlarged detail of one of the saws and cutter-heads, being a section on line 2 2 in Fig. 3. Fig. 3 is an enlarged section on line 3 3 in Fig. 14. Fig. 4 is a plan of the parts shown in Fig. 3. Fig. 5 is an enlarged detailed sectional view of one of the sprocket-wheel-shaft bearings. Fig. 6 is an enlarged detailed sectional view of one of the threadedsupports on which the transverse adjusting-screws are mounted. Fig. 7 is a view of-the other side of the said machine. Fig. 8 is a longitudinal view of the section on line 8 8 in Fig. 14:. Fig. 9 is a perspective of one of the adjustable guards for holding Specification of Letters Patent.

the cleats down upon the endless traveling work holder or carrier. Fig. 10 is a detailed sectional view of the portion of the device shown in Fig. 9. Fig. 11 is a longitudinal section on line 11 11 in Fig. 1 1. Fig. 12 isa transverse section on line 12 12 in Fig. 14. Fig. 13 is a perspective of one of the cleats or strips of wood, showing its ends step-mitered in the desired manner. Fig. 14: is a plan of my improved machine for stepmitering the ends of cleats or strips of wood or other articles. Figs. 15 and 16 are detailed sectional views of one of the chains and its support.

The frame or body A is adapted to support the shafts and other operative parts in suitably-elevated positions. Preferably the two sides of the frame are rigidly connected by the rods or braces a. The transversely-arranged shafts B and G are supported in bear- .ings Z) and 0 0 carried by the said frame. As

shown. the bearing 5 for one end of the shaft B is mounted on the end of a laterally-adjustable inner frame member D. Both of said shafts are preferably grooved substantially throughout their lengths. The two rotary screws E and F are arranged to extend across the machine and are supported in bearings e e and ff. In the inner frame member D these two screws extend through non-rotatable nuts 6 and f. (See Fig. 6.) Both the shafts and the screws are provided with means for preventing them from shifting endwise in their bearings in the two rigidly-connected sides of the frame. The shaft B is provided with sprockets Gr and G, the latter being adapted to slide along the spline or keyway in said shaft. With the arrangement shown the sprockets H and H are mounted on studshafts it and h, supported in bearings 72. and and b on the frame A and the adjustable frame member D. A sprocket-chain I connects the sprockets Gr and H, and a similar chain J connects the sprockets G and H.

The cutter-heads K and L are mounted on the shaft C, the cutter-head L being adapted for sliding movement along the spline or keyway in said shaft. Each cutter-head is provided with a circular saw, such as the saw 76. (Shown in Fig. 2.) The hub in of the cutterhead K is provided with oblique grooves adapted to removably receive the stepped cutters 76 and the cutter-head L is substantially the same in character. In this way the two cutter-heads taper toward each other. The cutter-head L has a sleeve Z, supported in a bearing Z on the frame member D, and the shaft C'is supported in this sleeve. Referring to Fig. 9, it will be seen that the bearing Z is integral with the arms Z and with the foot Z the latter having a notch Z. A spring-pressed guard Z is suitably supported by the arms Z and arranged just above the chain J and inside the cutterhead L. A similar but stationary guard M is secured to the bearing 0.

The chain-supports N and O are supported by brackets secured to the frame A and the movable frame member D. The said chains are preferably provided with lugs 2' and j.

As shown, the bearings c 0 are supported on the upper threaded end portions of the short ad usting-screws Pand Q, which are provided with bevel-gears 12 and q. A horizontally and transversely disposed adjusting-shaft R is supported in bearings r on the frame A and is provided with bevel-gears r and r adapted to engage the bevel-gears p and q. A handwheel r is provided for rotating the said shaft.

The end of the cutter-head shaft C can be provided with fast and loose pulleys Sand S. ilheqchain-shaft B can be provided with a pul- At one side of the machine the longitudinal adjusting-shaft U is supported in bearings u and u on the frame. This adjustable shaft is 'provided'with bevel-gears U2 and U3, adapted to engage the bevel-gears e and f secured to the ends of the screws E and F. A handwheel n is provided for rotating the shaft U. The guard V is secured to the frame A.

In operation the strips of wood are laid on the chain across the machine, and the direction of motion is such that the ends of the strips are cut off by the circular saws and the ends step-mitered by the cutters in the heads as the said strips are carried forward under the cutter-heads. The distance between the cutter-heads can be varied, according to the length desired for the cleats or strips of wood, by rotating the hand-wheel u, and the cutterheads, together with the shaft C, can be adjusted bodily up and down, according to the thickness of the cleats, by rotating the handwheel r It will be seen that the two lower portions of the foot Z straddle the shaft R and that this foot is adapted to move up and down in a recess in the frame member D. The lugs Z and j engage and carry the strips of wood forward, and the guards Z and M keep the same down in place on the chains, which latter are supported by the supports N and O, as explained.

It will be seen that the sliding connection between the inner or lateral frame member and the laterally-movable cutter-head not only permits the two cutter-heads to be simultaneously raised and lowered, these cutter-heads being supported independently of the movable frame member, but also permits the simultaneous lateral adjustment of the said cleatholding and cleat-cutting meansthat is to say, the simultaneous lateral movement of one chain and one cutter-head.

It will be seen that the knives or cutters have their base portions widened, flanged, or otherwise adapted to fit correspondinglyshaped oblique grooves in the periphery of the hub Zn. In this way each knife or cutter has practically a dovetail sliding connection with the hub upon which it is movably mounted.
